Abstract

The utility model relates to a powerless fluid measuring and controlling electronic meter. Mainly, by potential pressure energy when liquid /gas fluid flows, a miniature magnetoelectric generator is arranged at an ingress and egress channel in a casing, and a farad level capacitor is connected to an original voltage transforming storage unit to store electrical energy which is used by an original electronic sensing measuring and controlling integrated circuit board and an electromagnetic fluid control valve. Thus, a battery and alternating current can not be used. The utility model overcomes the trouble of battery replacement and the disadvantage of unsafety that a hole needs to be punched to lead a wire when the alternating current is used. The whole powerless fluid measuring and controlling electronic meter can be mechanotronics, and is fixed in a metal casing or a pipeline in seal. The powerless fluid measuring and controlling electronic meter does not have the tail of a power supply line like a mechanical meter, but has the functions of an electronic meter. The utility model has the advantages of firmness, compactness, reliability, longevity, safety, explosion prevention, and money economization, and is suitable for running water meters, coal-gas (fuel gas) meters, fuel meters, fluid thermometers /pressure meters, air volume meters, etc.

Fluid observing and controlling electronic instrument without power supply

Technical field

The utility model relates to a kind of fluid measurement electronic instrument, specifically, is to measure the improvement structure of electronic instrument about comprising water/gas/flow of oil.

Background technology

The electronic type fluid meters has more advantage than mechanical type fluid meters, it can numeral show more accurate, but teletransmission, may command, can with computer networking.Existing these electronic type fluid meters generally all are provided with the voltage transformation storage unit in its housing, electronic sensor observing and controlling surface-mounted integrated circuit and control valve for fluids, this just makes existing this class fluid measurement electronic instrument that a common shortcoming is arranged, need use battery or AC power to do the energy exactly, this is to using and installing and all brought inconvenience, when for example on pipeline, installing with the electronic type fluid meters of ac power supply, must burrow, perforation, grooving, discharging wire, connect the alternating current 220V power supply, thereby, safety is inadequately arranged, need construction and installation, need to consume electric power; Making battery-powered electronic type fluid meters then need change battery, is very much trouble, particularly also has the drawback that is unfavorable for environmental protection.

Content of the present invention

As mentioned above, the power supply that how to solve existing electronic type fluid meters is a technical problem to be solved in the utility model, and therefore, the purpose of the new shape of this practicality is to provide a kind of electronic type fluid meters without power supply.

It is reasonably to utilize to contain certain pressure energy in the tested fluid that the technology of the new shape of this practicality solves design, potential energy when utilizing fluid to flow, drive a newly-designed miniature magnetoelectricity Blast Furnace Top Gas Recovery Turbine Unit (TRT) generating, and through existing voltage transformation storage element, remove to supply with electronic sensor observing and controlling surface-mounted integrated circuit or fluid control and come work, like this electric energy that flow out to generate of fluid just be Electronic Instrument System active redundancy required electric energy, thereby can save and change battery or AC-powered, bring safety and convenience in the use.Summary is got up, and the technical solution of the utility model is as follows:

According to a kind of fluid measure and control instrument of the present utility model without power supply, comprise housing and be located at the interior voltage transformation storage unit of housing, and electronic sensor observing and controlling surface-mounted integrated circuit and fluid control, be characterized in: in instrument housing, on fluid turnover path, miniature magnetoelectric generator is housed, the kinetic energy generating that utilizes fluid to flow, and after being set, farad level electric capacity connects the voltage transformation storage unit in shell, to strengthen storage, this energy is supplied with electronic sensor observing and controlling integrated circuit and fluid control usefulness to electric energy.

Said microgenerator comprises group axle and coil, on the group axle, be provided with impeller, its work is driven by the fluid in the fluid turnover path, be provided with ferromagnetic material on the impeller sets zoarium that in fluid, rotates or directly have the super magnet magnetic pole, when rotated can cutting magnetic line, make set coil generating;

Said fluid is a tap water, therefore, according to the utility model, can make a kind of (tap water) electronic water meter without power supply;

Said fluid is combustion gas, therefore, according to the utility model, can make a kind of electronics coal (combustion gas) gas meter without power supply;

Said fluid is a fuel oil, therefore, according to the utility model, can make a kind of electronics without power supply (gasoline) fuel ga(u)ge;

Further, the utility model also has quantitative/timing unit of this electronic sensor observing and controlling surface-mounted integrated circuit of connection and fluid control, thereby can make a kind of quantitative/flow controller regularly without power supply, when reaching predetermined digital value, can close or open fluid control, i.e. list/bistable electromagnetic Fluid valve automatically;

Further, the utility model also can be provided with fluid temperature (F.T.)/pressure sensor, and its output terminal connects this electronic sensor observing and controlling surface-mounted integrated circuit, thereby can make a kind of electronic type fluid temperature (F.T.)/pressure without power supply/air measuring instrument.

As mentioned above, the utlity model has following advantage:

1. owing to miniature magnetoelectric generator is set and the super energy storage capacitor of farad level is set, make full use of the kinetic energy generating of fluid on fluid passage, overcome prior art and use alternating current 220V power supply or the existing drawback of dry cell power supply;

2. the utility model has a wide range of applications.
